CPC Class H04W

An agricultural data collection system may include a plurality of self-powered agricultural data collection devices disposed across an agricultural area. The agricultural data collection system may also include a plurality of self-powered agricultural output devices that control the distribution of one or more agricultural resources across at least a portion of the agricultural area. The plurality of self-powered agricultural data collection devices and the plurality of self-powered agricultural output devices may communicate wirelessly to selectively implement an agricultural management method that uses data collected by the self-powered agricultural data collection devices to provide agricultural resources where needed within localized agricultural areas within a larger agricultural area. At times, the agricultural management method may include an adaptive method that employs machine learning principles to optimize agricultural production within the agricultural area.

An electronic cigarette vaporizer that includes a heating element, a power source and an electronics module that manages the delivery of power, current or voltage to the heating element; the electronics module controls or delivers pulses of power, current or voltage to the heating element, such as PWM (pulse width modulation) with a high frequency 1-10 KHz switching frequency. The duty cycle of the PWM can be approximately 90% when heating; and 1-10% duty during a preheat; and 0% when the vaporizer is idle.

An exemplary subcutaneous medical device implanted within a patient uses a coil-less magnetic field sensor included within the subcutaneous medical device to detect a toggling sequence between a presence and an absence of an externally-generated static magnetic field. The toggling sequence is representative of a digital data stream according to a digital wireless communication protocol. The subcutaneous medical device identifies, based on the detected toggling sequence and in accordance with the digital wireless communication protocol, a multi-bit command encoded within the digital data stream represented by the toggling sequence. The subcutaneous medical device further performs, in response to the identifying of the multi-bit command, an action associated with the multi-bit command. Corresponding methods and a corresponding external controller are also disclosed.

A virtual reality tracking system accurately determines one or more controller orientations using data from tracking cameras and/or an inertial measurement unit (IMU) embedded in each controller. Each controller has two or more distinctive light-emitting tracking markers. The tracking system determines the locations of the tracking markers based on the location of tracking markers in tracking camera's images. The tracking system determines the controller orientation using the locations of the tracking markers and orientation data from the IMU. When the camera views of the markers are obstructed the tracking system relies solely on the less-accurate orientation data from the IMU.

Systems and methods for charging an electric battery of a vehicle are provided. The vehicle includes a battery for powering an electric motor of the vehicle. A controller of the vehicle is provided to interface with a battery and to enable control of charging of the battery. The vehicle includes a communications interface for enabling wireless communication with a server, and the server is configured to manage a plurality of user accounts for users. The server is one of a plurality of servers, and the servers providing access to cloud services regarding vehicle use and metrics.

Embodiments are disclosed for systems for a vehicle. An example system for a vehicle includes a head-up display and a circuit, which is connected to the head-up display, wherein the head-up display is configured to project an image onto a front windshield of the vehicle or onto a separate combiner, wherein the circuit is configured to output image data to the head-up display, whereby the image data have a set of objects which include messages for the user, to determine a user's workload level, based on a set of driving conditions, to switch between at least one first workload mode and a second workload mode based on the level, whereby the second workload mode is assigned a higher level than the first workload mode, and in the second workload mode to reduce at least one object, which is output in the first workload mode.
